Packing cushion

Abstract

A packing cushion includes a base and a plurality of sidewalls coupled to the base. The plurality of sidewalls interconnect with each other and cooperate with the base to form an accommodating space. First and second cushion portions protrude from an inner surface of the base and an inner surface of one of sidewalls respectively. The first cushion portion includes a first surface. The second cushion portion includes a second surface. A contour defined by the first surface matches with at least a part of an object to be packed. When the object is packed in the receiving space, the first surface contacts with at least a part of the object to provide a first cushioning, and when the object is subjected to an impact to deform the first cushion portion, the second surface contacts with the object to provide a second cushioning.

1. A packing cushion for packing an object, the packing cushion comprising:
 a base; and 
 a plurality of sidewalls coupled to the base, the plurality of sidewalls interconnecting with each other and cooperating with the base to form an accommodating space; 
 wherein an inner surface of the base defines at least one first protruding block, the at least one first protruding block is arranged adjacent to one of the sidewalls, an inner surface of the sidewall adjacent to the at least one first protruding block defines at least one second protruding block and at least one third protruding block, each first protruding block is arranged between two adjacent a second and third protruding block, a contour defined by the at least one first protruding block matches with at least a part of the object to be packed, when the at least one first protruding block is in an original state, the at least one first protruding block contacts with the object to act as a first cushioning, and the at least one second protruding block and the at least one third protruding block contact with the object to act as a second cushioning when the first protruding blocks deforms enough, wherein a slot within the accommodating space is defined between each first protruding block and the sidewall adjacent thereto to provide a buffer space for when the at least one first protruding block deforms. 
 
     
     
       2. The packing cushion of  claim 1 , wherein the at least one first protruding block is substantially D-shaped. 
     
     
       3. The packing cushion of  claim 1 , wherein a receiving recess is defined between the at least one second and third protruding blocks, the receiving recess corresponds to one of the at least one first protruding block. 
     
     
       4. The packing cushion of  claim 3 , wherein the receiving recess is substantially C-shaped. 
     
     
       5. The packing cushion of  claim 3 , wherein a part of the at least one first protruding block is received in the corresponding receiving recess. 
     
     
       6. The packing cushion of  claim 5 , wherein the slot is formed between the at least one first protruding block and the corresponding receiving recess. 
     
     
       7. A packing cushion, comprising:
 a base; and 
 a plurality of sidewalls coupled to the base, the plurality of sidewalls interconnecting with each other and cooperating with the base to form a receiving space; 
 wherein at least one first cushion portion protrudes from an inner surface of the base and arranged adjacent to one of the sidewalls, at least two second cushion portions protrude from an inner surface of the sidewall adjacent to the at least one first cushion portion, each first cushion portion is arranged between two adjacent second cushion portions, the first cushion portion comprises a first surface, the second cushion portions comprise a second surface, a contour defined by the first surface matches with at least a part of an object to be packed, when the object is packed in the receiving space, the first surface contacts with at least a part of the object to provide a first cushioning, and when the object is subjected to an impact to deform the first cushion portion, the second surface contacts with the object to provide a second cushioning, wherein a slot within the receiving space is defined between each first cushion portion and the sidewall adjacent thereto to provide a buffer space for when the at least one first cushion portion deforms. 
 
     
     
       8. The packing cushion of  claim 7 , wherein the second cushion portion integrally protrudes form the sidewall adjacent to the first cushion portion. 
     
     
       9. The packing cushion of  claim 8 , wherein the sidewall adjacent to the first cushion portion defines a receiving recess, the receiving recess is arranged between two adjacent second cushion portions, and a part of the first cushion portion is received in the receiving recess. 
     
     
       10. The packing cushion of  claim 9 , wherein the slot is defined between the first cushion portion and the receiving recess corresponding to the first cushion portion. 
     
     
       11. The packing cushion of  claim 8 , wherein the second surface is sandwiched between the first surface and the sidewall adjacent to the at least one first cushion portion. 
     
     
       12. The packing cushion of  claim 7 , wherein third and fourth cushion portions protrude from the inner surface of the base. 
     
     
       13. The packing cushion of  claim 12 , wherein the third and fourth cushion portions are operative to support a top or bottom portion of an object, the fourth cushion portion acts as a third cushioning to absorb impact energy, and when the fourth cushion portion deforms, the third cushion portion acts as a fourth cushion to absorb also impact energy, whereby the fourth cushion portion is protected from deforming too much and losing its ability to rebound. 
     
     
       14. The packing cushion of  claim 11 , wherein the second surface is parallel to the first surface.
